Would it have made any difference if the women had been killed? From what I can see, probably not really. If you can get away with the chief finding it "very concerning that officers fired before adequately identifying a threat; fired without adequately identifying a target and not adequately evaluating cross fire situations", resulting in civilian injuries and other targets being hit, and just face some additional training — I don't think bodies would have made a difference at all.
Don't get me wrong — I wouldn't want to be guarding a house and then hear a loud noise that maybe sounded like a gunshot and see a vehicle driving past. But, then, I'm not paid and licensed by the city to carry around deadly force with the expectation that it will be used only when actually called for. If you can't do that, no matter how spooky a night or how worrisome it is that there's a cop-killer out there, then additional training doesn't mean diddly.
